English(EN) Select or Rewrite: Oracle-Guided Fine-Tuning for Generative ASR Post-Editing from N-Best Hypotheses

新的微调方法通过LLM增强ASR后编辑

研究人员开发了一种名为Oracle引导微调的新方法,以使用大型语言模型改进自动语音识别(ASR)后编辑。该技术利用N-best假设来创建精选的训练数据,包括校正、正则化器和硬负例,以教会模型何时选择最佳假设或重写文本。该方法旨在降低词错误率并抑制幻觉,在专有数据集上使用约30亿参数的模型显示出有希望的结果,尽管在公开的Common Voice数据集上的收益不太确定。 AI

影响 这项研究通过改进大型语言模型处理文本校正的方式,有望带来更准确、更可靠的ASR系统。

    选择或重写:基于N-Best假设的生成式ASR后编辑的Oracle引导微调

    arXiv:2610.15056v1 Announce Type: cross Abstract: Large language models can post-edit ASR by using linguistic context to compare N-best hypotheses and rewrite the transcript when needed, often improving WER without retraining the recognizer. However, prompt-only correction is bri…
